MACHINE FOR SURFACING BUTCHERS BLOCKS.

To all whom it mayconcern:

Be it known that we, OscARFAosER and FRANK P. 'FAUSER, both, citizens of the United States, residing at. Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Machines for Surfacing Butchers Blocks, of which the following is a specification. 7 p I c This invention has reference more par- V to a machine for resurfacing butchers" blocks, which may be transported from place to place, and set up for operation where the block is located.

The obJect of the invention is to provide a machine which is self-supporting nd may be setup with the block in the interior of the frame of the machine.

A further object 1s to provide a machine for this-purpose with a plurality of adjustable supports, whereby the machine may readily be ;adjusted relatively to the surface of the blockas desired.

A further object is to rovide a frame which is collapsible, or may l oe knocked down to facilitate transportation from place to place, and admission into a building and which can conveniently be set up around the block.

A further object is the provision of a thesurface of the block and provided with the resurfacing member directly connected thereto.

A further object is the provision of. antifriction supporting means for the parts movablein the operation of the device whereby operation of the device is facilitated.

The invention also has other objects and features of improvement, which will appear from the following specification taken in connection with the drawings, and which are particularly pointed out in the claims.

In the accompanyingdrawing, which illustrates our invention,- I

is an ordinary may be square as shown, round, or any other suitable form, as the 'machine is supported independently thereof. The frame of the machine is adapted to be set up around the block and consists of the twoend sections, which are detachably connected, as hereafter explained. One of these end sections consists of the vertical pipe membe rs2, with the pipe Ts 3 at the upper ends, whichv are connected by means of the pipese, The lower ends of the pipes 2 are provided with the couplings 5, which may be connected by a pipe similar to, and parallel with the pipe 4: for thoroughly bracing this frame and therev are the short pipes 6 screwed into the couplings 5 in line with, and forming a continuation of pipes 2. i

The opposite end section of the frame is similarly constructed, except that the top cross pipe 46*, has the bearing bracket 7 interposed in the length thereof and the brace pipe Sdhas a T interposed in the length thereof and there is a cross pipe 9 connectmg the said T with an extension 10 of the Patented Dec. 3, 1918.

butchers block, which bearing bracket 7, whereby the said bearing bracket is held in the proper upright position. The Ts 5 are also slightly different than the Ts 5, as hereafter mentioned. The lower ends of the pipe sections 6 are prov vided with collars 11 which are clamped or otherwise secured on to the lower end of the'said pipes, said clamps being provided with opposite pawls 12, which are connected by means of the spring 13, to bear inwardly and engage the ratchet faces of an adjustable foot member. This foot member has the flanged or disk shaped part 14, which supports the device and may be provided with the perforations indicated by dotted lines at 15, wherebythe device may be secured to the floor if desired andthere is a stem 16 which extends vertically from the disk 1 1 and is telescoped by the pipes 6 and 2 and has the annular ratchet faces 17 which are engaged by the pawls 12 to. support the frame of the machine in the desired position of elevation. Y I

For detachably eonnectingthe end sections there are a pair of parallel angle iron rails 18, which have one flange of theangle iron laid horizontally .and connected to the corresponding ends of the two sections by means of cap screws or bolts 19, which pass-through the horizontal flange of the angleiron at its ends and screws into, the upper end of the.

couplings 3. I The other flange of the angle iron extends vertically and forms a track upon which is supported the framefor' carrying the mechanism for resurfacing the block. A. pipe brace 2 0 is provided at each side to connect the two end sections, said pipe at one end having athreaded connection with the coupling 5 and at the other end is merely 1n- :s'erted into the coupling and secured by means of the pif1f21, passed'therethrough;

the machine rendered in condition for transportation.

Mounted .upon each of the rails'l8 is an end plate 22, "each of which has a pair of depending flanges 23, the lower ends of fwhich are provided with a stub bolt 24,

which projects under the angle iron 18, as

, shown'in Fig. 4, and holds the frame from removal. Each of the flanges 23 has a companion' flange 25 opposite and spaced therefrom between which is pivotedly mounted a roller 26, which travels on the vertical flange of the angle iron 18. The two plates 22, are connected and spaced by means of the three rods 27 which are secured to the plates-by means of the clamp nuts 28, and there is a screw shaft 29' journaled in, and extending between the two plates; This screw shaft 29 has at one end, a ratchet wheel 30, which may be locked by means of a reversible ratchet pawl 31, for holding the screw shaft 29 against turning, and thereis a handle 32 on this shaft for imparting rotation thereto.

Mounted upon the rods 27 intermediate of the side plates 22, is a casing 33, 'which'is adapted to inclose a motor 34, which is supported by the said casing 33 as at 35 or otherwise secured thereto, so that the shaft 36 thereof is positioned vertically and projects through and beneath thebottom of the said casing. is adapted to have a saw 37 secured thereto, the said saw being attached to the sleeve 38, in such a manner that the underface thereof is perfectly smooth and permits the operation of the saw against the surface of the block. This sleeve is preferably attached by means of a cap screw 39 or otherwise so that it may be very readily removed or replaced. The rods 27 which pass. through the casing 37 support the said casing and permit sliding movement'from end to end of the rods, and the screw shaft 29 is also inserted through the said casing'and has a threaded relation with a sleeve or'nut 40, which is boltedor'otherwise secured tothe wall of the casing. Thus it will'be observed that the turning of the screw shaft 29) by its engagement with the nut40, will cause the casing The .lower'end of this shaft 37 and motor therein toqmjove longitudinally along the rods.

This screw shaft29 is designed to regulate the lateral depth of thesaw against the surface part of the block to be removed by advancing the motor 34 and saw 37 laterally within; the frame, and when ithas been turned to the. proper position it is locked against further turning by engagement of the pawl 31 with the ratchet wheel 30.

For moving the sawing mechanism length wise of the supporting frame and across the face of the block 1, there are provided the brace rods 41, which at their outer ends are attached to the plates 22, and at the inner adjacent ends are connected to a conphng 42. Ascrew shaft ;43which is of suflicientlength toinove the sawing mechanism from one end to the other of the sup- 1 porting frame, is companion bearings 44-and-45 of bearmg bracket 7 and the inner end of this screw shaft is adapted to be; inserted into the-coupling 42, and securedtherein by means of the pin. 46, whereby it may be readily assembled, and taken apart. Forfmoving this screw shaftv lengthwise to cause corresponding movement of the sawing mechanism, there is a spur gear 47 positioned intermediate of;the bearings 44 and 45 and threaded internally so asjto screw upon the shaft 43. A gear 48=ismounted upon an arm of bracket 7 in mesh with the spurgear and provided with a handle 50, whereby it may beturned .place in a knock-down condition which passed looselythrough makes it easier to handle and readily taken into a building, which would be; diflicult and sometimes impossible in its assembled form. To use the machine,'the end sections areset up, one on each side of theblock to be resurfaced. The pipes 20 are then screwed into j the coupling 5 and the other ends of these pipes 'are inserted in the corresponding couplings 5, of the opposite end section, and secured therein by means of the pins 21.

Theangle'iron rails 18 are then placed in position and attached by (means of the cap screws or bolts 19.; The motor carriage is then mountedon the-rails'IS (the stub bolts 24 having beenjpreviouslyremoved) and the stub bolts 24 are then secured in place to hold the said motor frame on the track. The screw 43 is then inserted, through the bearings, 44'and 45, and intermediate spur gear 47 and the end thereof secured to the coupling 42 by means of-the pin46; The saw is then adjusted to one side of the block and thefoot plates 14 are adjusted by means of the ratchet pawls. 12 to position the sawso that it will take ofi'the required" amount to resurface the topofftheblock: The saw is then adjusted by'means of the handle 32 to make the required lateral depth of cut, and the saw having been 'set in operation, the

motor frame is caused to move across the.

. cut ofl. does not readily break loose, it may readily .be broken off by striking with a hammer or may be cut off with a chisel or hatchet as no doubt will be readily understood. Y

After the block has been entirely resurfaced, the machine may be knocked down by reversing the steps in assembling and the machine is then ready for transportation.

It is intended and preferred that an elec- ,tric motor be employed for use with this machine and a switch 52 may be provided at one side of the motor casing 33, from which the circuit wires53 lead to any convenient source of electric power, the said wires being of'suflicient length to permit the required movement of the motor in the operation of the machine.

From the foregoing it will be noted that the machine is cap-able of use'in connection with blocks of different sizes and shapes;

' that the frame is adapted to be knocked down for transportation and can be built up or set up around the block so that it does not have to be lifted over or clamped to the block; that it is supported independently of the block and adjustable at the four corners to provide the required relation of the new surface to the block and also to regulate the depth of the cut, and that the motor is directly connected to the saw, whereby the greatest efliciency may be obtained.

WVhat we claim is 1. A resurfacing machine comprising a frame adapted to be positioned about a meat block or the like and having a pair'ofupright vertically adjustable end sections one of which including an intermediate bearing bracket at its upper end, a pair" of angle rails detachably secured at opposite ends to the upper corners ofthe end sections and forming upper braces, a pair of lower braces secured at one end to one of the sections,
